問題点があった。However, in the structure of the lower case 3 as shown in FIG. 3, the motor noise of the fan motor 6 generated when the fan 5 is driven,
The problem that noise such as wind suction sound generated when the wind passes through the heat exchanger 4 is reflected on the inner surfaces of the upper case 2 and the lower case 3 and leaks to the outside of the main body 1 through the suction port 1a and the air outlet 1b. There was a point.

特に、本体１は後部座席（図示せず）よりも前部座席14
に近い場所に配置されるために、前部座席頭部位置14a
近辺に配される吸込口1aから漏れる前部座席14搭乗者に
対する騒音が問題となっていた。In particular, the main body 1 has a front seat 14 rather than a rear seat (not shown).
To be located closer to the front seat head position 14a
There was a problem of noise for passengers in the front seat 14 leaking from the suction port 1a arranged in the vicinity.

課題を解決するための手段 上記問題点を解決するために本発明は、熱交換器より風
上側のケース内底面に、底面から上方へ伸びる防音壁を
設けるものである。Means for Solving the Problems In order to solve the above problems, the present invention provides a soundproof wall extending upward from the bottom surface on the bottom surface in the case on the windward side of the heat exchanger.

る。Action The action of this technical means is as follows. By providing a soundproof wall extending upward from the bottom surface on the bottom surface in the case on the windward side of the heat exchanger, it is possible to block the noise reflected in the case and heading toward the front seat head position.

実 施 例 以下、本発明の一実施例を添付図面にもとづいて説明す
る。Example Hereinafter, one example of the present invention will be described with reference to the accompanying drawings.

置されている。10,11は前記熱交換器９の後に設けられ
たクロスフローファンとファンモータである。13はこれ
らにより構成された自動車用空気調和装置である。In FIGS. 1 and 2, 7 is an upper case and 8 is a lower case, which form a suction port 13a and a blowout port 13b. A heat exchanger 9 is obliquely installed in the upper and lower cases 7 and 8. Reference numerals 10 and 11 are a cross flow fan and a fan motor provided after the heat exchanger 9. Reference numeral 13 is an air conditioner for an automobile constituted by these.

前記下ケース８において、前記熱交換器９の後方には防
音壁12が下ケース８の端面より離れる斜め上方向に向け

示すように前記防音壁12によりさえぎられる。In the lower case 8, a soundproof wall 12 is installed behind the heat exchanger 9 in an obliquely upward direction away from the end surface of the lower case 8, and noise transmitted in the seat head position direction is indicated by an arrow A. It is blocked by the soundproof wall 12.

発明の効果 本発明によれば、熱交換器より風上側のケース内底面

かう騒音を遮るため、前部座席搭乗者に対する騒音を低
減することができる。EFFECTS OF THE INVENTION According to the present invention, by providing a soundproof wall extending upward from the bottom surface on the inner bottom surface of the case on the windward side of the heat exchanger,
Of the noise reflected in the case, the noise directed toward the front seat head position is blocked, so that the noise for the front seat occupant can be reduced.

また本発明は、ケース内底面に、防音壁を設けるのみで
あり、特に、部品点数を増やすこともないため、作業工
数の増加による作業性の低下を招くこともない。Further, according to the present invention, only the soundproof wall is provided on the inner bottom surface of the case, and since the number of parts is not particularly increased, the workability is not deteriorated due to the increase in the number of working steps.
